Common Mode Chokes come in a variety of sizes, shapes and applications, and are used for attenuating electromagnetic interference (EMI) and common-mode noise in electronic circuits. The PM3700-70-RC Common Mode Choke is a specific type of Common Mode Choke designed for EMI filtration and power line noise attenuation. Common Mode Chokes are composed of multiple heavy gauge wires twisted together in a specific arrangement to provide a high-frequency circuit with significant attenuation characteristics.The PM3700-70-RC Common Mode Choke features a core size of 37 mm diameter and 70 mm height, with an outer shell made of injection-molded plastic resin. The PM3700-70-RC has an impedance range from 5 to 250 ohms, and offers high common mode noise and surge suppression capacity with a current rating up to 11 Amps. The product is suitable for power supply lines, DAB, Wi-Fi, Zigbee, Bluetooth, PLC, High-speed EMI filter, Uninterruptible Power Supply (UPS), and Automotive Electronics.The working principle of a Common Mode Choke involves combining common-mode noise and electromagnetic interference (EMI) to reduce or eliminate them from the signal path. Common-mode noise is typically produced by switching power supplies, motor drives, and other sources of electrical noise. The Common Mode Choke utilizes its multi-conductor winding design to absorb the common-mode noise and reduce its occurrence. The design works by creating a flux link between the two windings that are connected in series, and the two signals then pass through the common-mode winding. This creates an inductive field that slows down and attenuates common-mode noise.Additionally, Common Mode Chokes also offer dissipation layout protection. This is achieved by allowing signal current to flow through the choke’s internal conductors in a single direction, preventing current from flowing in the opposite direction and potentially damaging components. By doing so, it helps protect sensitive electronic components from high-frequency surges.Overall, the PM3700-70-RC is an efficient, reliable and high-performance Common Mode Choke that provides filtration for EMI/RFI and power line noise. Its smaller core size and multiple-conductor winding design make it a valuable component for use in automotive electronics, DAB, and Wi-Fi applications. The PM3700-70-RC Common Mode Choke offers robust protection against current surges and attenuates common-mode noise, providing the ultimate circuit protection for your electronic components.
